The Shanghai tin price is expected to be weak first and then strong. Investors are advised to mainly buy on price dips, paying attention to support and resistance levels [3]. Summary by Directory Part 1: Spread and Inventory Situation - The basis of Shanghai tin is positive and the monthly spread is negative, both within a reasonable range. Due to the Fed's future interest rate cut and halt of balance - sheet reduction expectations and the slow resumption of tin mines in Wa State, Myanmar, investors are advised to wait and see for arbitrage opportunities [7][9] - The (0 - 3) contract spread of LME tin is negative and the (3 - 15) contract spread is positive, both within a reasonable range. The Shanghai - London tin price ratio is below the 50% quantile of the past five years. Due to the Fed's expectations and the decreasing inventory of refined tin in LME, investors are advised to wait and see for arbitrage opportunities [10] - The inventory of refined tin in SHFE decreased compared with last week; the social inventory of tin ingots in China decreased compared with last week; the inventory of refined tin in LME increased compared with last week; the total inventory of refined tin at home and abroad decreased compared with last week [12] Part 2: Mid - upstream Supply Situation - The daily processing fee of domestic tin concentrate is oscillating downward, indicating a tight supply expectation of domestic tin mines [18][19] - The production (import) volume of Chinese tin mines in October increased (increased) month - on - month.
